Misfueling occurs when the wrong type of fuel is pumped into an aircraft’s tanks. It could be that jet fuel gets pumped instead of gasoline, gasoline instead of jet fuel, automotive gas instead of aviation gas, automotive gas containing ethanol instead of auto gas with no additives, or something else yet to be devised by a creative fueling person.
Recently, the misfueling issue attracted attention because of an accident that occurred on March 2, 2008. Shortly after taking off, a single-engine Cirrus SR22-G3 Turbo crashed into the upper floors of a condominium building in Rio de Janeiro, Brazil. All four people on board were killed. The SR22 was marked with the word “Turbo,” referring to its turbocharged engine. Preliminary information indicated that the lineman who fueled the airplane has mistakenly interpreted the word “Turbo” to mean that the airplane was powered by a turbine engine. Therefore, he fueled the airplane with Jet A.
